Chris Hemsworth posts rare photo of twin sons: '#littlelegends'

March 7 (UPI) -- Chris Hemsworth gave fans a rare glimpse of his twin sons Monday.

The 33-year-old Australian actor shared a sweet picture of Tristan and Sasha, his 2-year-old sons with wife Elsa Pataky, holding hands after returning home to Byron Bay, Australia.

"My son said to his brother 'Tristan hold my hand so you don't get eaten by a crocodile' #mykids #littlelegends @australia #byronbay," he captioned the snapshot for his 9 million Instagram followers.

The Thor star and Pataky, who married in 2010, are also parents to 4-year-old daughter India Rose. The family returned to Australia last week, and have since enjoyed an outing to their favorite swimming hole.

"We are in paradise! / estamos en el paraíso! #lovethisplace #happykids #bestbathever," Pataky wrote on her own account Friday.

Hemsworth and Pataky, a 40-year-old Spanish actress, moved to Australia in 2014. Pataky said in an interview with the Herald Sun in October that the move was "the best thing" she's done in her life.

"For me it's a dream living in nature, especially with kids. I want that environment for them," she shared.

"We are trying to be normal people ... [with] no photographers and people following you," the star explained. "We live on a property in the mountains in the middle of nowhere, so we don't have that problem anymore, and that's what we wanted."

Hemsworth will next star in Thor: Ragnarok, which opens in theaters Nov. 3. He is also slated to reprise Thor in Avengers: Infinity War, which co-stars Robert Downey, Jr., Scarlett Johansson, Chris Pratt and Benedict Cumberbatch.
